- The CMC dislocation should be anesthetized with an intra-articular injection, and then closed reduction should be performed with traction [1,4].
- Immobilize the joint with a thumb spica splint with the first metacarpal held in abduction and extension with the wrist in pronation. Closed reduction is often unstable [1-6].
- The patient should have follow-up arranged with a Hand Specialist within 3-4 days [1,7].
